Nothing really is around there, unfortunately - I don't believe there are any hechshered places in Westchester outside standard take-out places. But if you go to Riverdale (about 15-20 minutes away), there are a few nice sit down places.

Also in Scarsdale, there is a dairy Seasons location (called the Gourmet Chef) which has take-out food with a couple of tables I think. It is basically a dairy deli counter. There's also a new vegetarian/vegan restaurant in that same shopping center. It has wraps, smoothies, etc. I don't recall if it's vegetarian or vegan. It's called ANDY'S PURE FOOD and it's certified by Vaad HaRabbonim of Queens.
